• Windows: Provides robust keyboard and mouse customisation options, Eye Control, and extensive support for third-party peripherals, making it ideal for users who need adaptive hardware integration.
• ChromeOS: Offers basic voice navigation and external device support, but relies more on third-party tools for advanced features, making it better suited for users with less intensive mobility needs.
